Design a heat exchanger that has an overall heat transfer

Question

Hypothesis:

The Um Elnar desalination plant would like to condense steam generated from the thermal desalination process to about 30^oC. The cooling sea water inters the heat exchanger tube of 1.5 cm diameter at 18 ^oC at a rate of 2200 kg/hr.

Given

- Water @ 30 ^oC has hfg = 2670 J/kg.K
- Cooling water @ 18 ^oC has cp = 4180 J/kg.K

Problem:

You are asked to design a heat exchanger that has an overall heat transfer coefficient of 300 W/m².K. Then calculate the rate of heat transfer.

Assumptions:

- You can select any type of heat exchanger for the design
- You will need to assume the length of the tube
- If you select shell and tube HX then you will need to assume the passes of the tube and shell sides and the number of tubes

Deliverables:

- A complete report that shows the details of the design
o Technical Report
o Choice justifications of:
    Type of HX selected
    The assumptions made base on what sense
o Show detailed calculations with explanation of the results and outcomes
    You can validate your detailed calculation and results by using a HX Design tool if you wish
o Suggestions and conclusion
- Design diagram or schematic of the HX identifying al the conditions
